The mining bees are a large group of European bees which are solitary meaning they build nests and care for broods alone. Andrena bicolor, known more widely as Gwynne's Mining Bee, is a small mining bee that's present across many parts of the world, including Europe, America, Central Asia and Russia. These bees are polyectic, which is a fancy term for a generalist pollinator, and that they enjoy the nectar of many flowers! They thrive in woodland and open woodland habitats.

Traits

These are hairy bees capable of pollinating many flowers a day.

Appearance

Adults: They usually possess lots of hair, showing similarities to a carder bee. They're small (about 1cm), and the males smaller again. The thorax hairs are golden-brown, but the abdomen a shiny black-brown with yellow and thin, faint, stripes. Sound identification is hard to achieve with mining bees because of all of their similarities. Larvae and Eggs: They reside beneath the ground where females have dug individual chambers. They are sealed in with enough pollen and nectar to keep them going until they have developed into mature bees.
